Windows 10 tablet won't turn on

I have a RCA Cambio 10.1" Tablet with Windows 10. It's one of those that includes a detachable keyboard.

About two weeks after purchasing the tablet, it just stopped powering on. When I plug it into the charger, the red light on it lights up so it's not dead. It just won't turn on. I've tried several things I've found online but none have worked. One supposed fix instructed me to hold down the volume button on the tablet, but it doesn't have one
The volume is on the detachable keyboard.
